Increasing organizational effectiveness: An examination of teacher leadership, collective efficacy, and trust in schools

This study explored the relationships of teacher leadership, collective efficacy, and trust throughout the school. This study took place in two school districts where data were collected from the Teacher Leadership Inventory, Omnibus T-Scale, and Teacher Collective Efficacy Belief Scale. Findings indicate a strong positive relationship between the three variables. Findings support the hypothesis that teacher leadership is a larger organizational construct, extending beyond the roles of individual teachers.
